[0002] 在火场等高温强热环境下,存在的最主要的潜在的危险,包括:火场的高温环境, 尤其是辐射热对人体的烧伤危险;防护装备器具被火焰引燃以及接触高温物体表面引起高速热传导,造成人体烧伤的危险等。 [0002] On the scene at high temperature and strong thermal environment, the presence of the main potential hazards, including: fire in a high temperature environment, especially radiant heat to the body burn hazard; protective equipment appliance is ignited and the flame contact with hot surfaces caused by high speed thermal conductivity, dangerous body burns and the like. 因此,为不致灼伤并正常工作,消防及特殊工作人员应穿着功能服装进行有效的隔热防护。 Therefore, in order not to burn and work, fire and special staff functions should wear protective clothing for effective heat insulation.

[0003] 资料表明,由明火火源产生的热流除少部分(低于30%)对流外,多以电磁波形式传播的辐射热向四周散热。 [0003] The data show that the heat generated by the naked flame sources, only a small portion (less than 30%) convection, the radiant heat as electromagnetic waves propagate more heat to the surrounding. 由于辐射热穿透力强,很容易造成人体烧伤或灼伤,因此消防类防火绝热织物的重点在于减少辐射热渗透,降低热传导,使防护服深层升温速度减慢。 Since the radiant heat penetration, it is easy to cause the body burns or burns, fire-resistant insulating fabric therefore fire focuses on reducing radiant heat penetration, reduce heat conduction, so that protective clothing deep warming slows down. 故而,防火绝热织物不仅要表面对辐射热具有高反射性能,而且本身要具有高吸耗能和快速散热的功能,还要耐火、耐高温,以实现对火源或热源的高效隔绝和对人体的安全有效防护。 Therefore, not only to the surface of the fabric fireproof insulation to radiant heat with high reflective properties, but also in itself to have a high energy and fast heat absorbing function, but also fire-resistant, high temperature, in order to achieve an efficient source of fire or heat isolation and on the human body safe and effective protection.
